Draw the corresponding steady trajectory of the Schaefer model (1) with the Beverton-Holtdynamics(4) and h(t) = he. Pick up two diﬀerent initial conditions in the neighborhood ofthe equilibrium biomass Be. Draw the corresponding trajectories. Does the ﬁgure conﬁrm ornot the fact that the equilibrium biomass Beis attractive?

Recall that, for an equilibrium, being stable or attractive are unrelated notions.

Question 3Does the ﬁgure conﬁrm or not the fact that the equilibrium biomass Beisstable? Be speciﬁc in your justiﬁcations. What can you say about asymptotic stability of theequilibrium biomass Be?
